We initiate a fundamental study of modal-plasmonic interactions in nanostructured resonance elements with the aim to develop new hybrid multiparametric sensors. The proposed hybrid sensor operates under guided-mode resonance (GMR) and surface-plasmon resonance (SPR) in unison. Numerical simulations of gold-integrated…
The Onsager theory of hard rod dispersion in a neutral solvent is extended to a case of two-component dispersion consisting of both non-magnetic and magnetic rods. It was found that the alignment of magneto-sensitive dispersion component by a magnetic field leads to the alignment of non-magnetic component in the dispe…
Considering the importance of thorium data and concerning about the accuracy of Th232 cross section library, a series of experiments on thorium critical core with different neutron spectra has been implemented at Kyoto University Critical Assembly (KUCA). Reactivity worth of control rod and thorium sample was measured…
We employ a Monte Carlo simulation scheme based on the bond fluctuation model to simulate template polymerization via controlled polymerization scheme involving copolymerization of free monomers (A) and monomers bound to a template (B) that consists of linear or ring-like substrates with equidistant sites occupied by…
In the past decade, the C60-based ion gun has been widely utilized in the secondary ion mass spectrometry (SIMS) analysis of organic and biological materials because molecular secondary-ions of high masses could be generated by cluster-ion bombardment. This technique furthers the development of SIMS in bioanalysis by…
Abstract Along with X‐ray diffraction measurements, 25Mg solid state NMR experiments were performed in natural abundance at 9.4 T on crystalline and mechanically milled samples of MgO, Mg(OH)2, MgF2, and magnesium hydroxide fluorides Mg(OH)xF2–x prepared on mechanochemical and sol‐gel syntheses routes. In addition to…
The theory of the stationary Josephson tunnel current ${I}_{c}$ was devised for junctions involving superconductors partially gapped by biaxial or unidirectional charge density waves (CDWs) and possessing a superconducting order parameter of $d$-wave symmetry. Specific calculations were carried out for symmetric junct…
We report the installation and performance evaluation of a probe aberration-corrected high-resolution JEOL JEM-ARM200F transmission electron microscope (TEM). We provide details on construction of the room that enables us to obtain scanning transmission electron microscope (STEM) data without any evident distortions/n…
Colloidal suspensions of plate-like particles undergo a variety of phase transitions. The predicted isotropic/nematic transition is often pre-empted by a sol/gel transition, especially in suspensions of the most commonly used natural swelling clay montmorillonite (MMT). A number of factors, including charge interactio…
We fabricated large area (>1 × 1 cm2), epitaxial Fe nanowire arrays on MgO(001) substrates by nanoimprint lithography with a direct metallization of epitaxial materials through a metallic mask, which avoided the disadvantageous metal-etching process in conventional methods. The magnetization reversals, as revealed by…
Abstract A new diblock copolymer composed of a regioregular block of poly[3‐[2‐(2‐methoxyethoxy)ethoxy]methylthiophene], bearing as side‐chain a hydrophilic substituent, and a regioregular block of poly[3‐(1‐octyloxy)thiophene], is prepared and characterized. The properties are compared with those of a related copolym…
BACKGROUND: Stable initial fixation of a total joint arthroplasty implant is critical to avoid the risk of aseptic loosening and premature clinical failure. With implant motion, a fibrous tissue layer forms at the bone-implant interface, leading to implant migration and periprosthetic osteolysis. At the time of implan…
We exploited the biomimetic approach to generate constructs composed of synthetic biphasic calcium phosphate ceramic and extracellular matrix (SBC-ECM) derived from adult human dermal fibroblasts in complete xeno-free culture conditions. The construct morphology and composition were assessed by scanning electron micro…
Abstract The alkaline earth metal compounds AETMg2 and AETCd2 (AE = Ca, Sr; T = Pd, Ag, Pt, Au) were synthesized by induction‐melting (or in muffle furnaces) of the elements in sealed niobium ampoules. The new phases were characterized by powder X‐ray diffraction. The structures of SrPdMg2 and SrPdCd2 were investigate…
The ${}^{241}$Pu(n,f) cross sections have been determined by the surrogate ratio method in the equivalent neutron energy range 11.0--16.0 MeV by using ${}^{238}$U(${}^{6}$Li,$d$)${}^{242}$Pu and ${}^{232}$Th(${}^{6}$Li,$d$)${}^{236}$U transfer reactions at E${}_{\text{lab}}=39.6$ and 39.0 MeV, respectively. Results ha…
Optical tweezers are exciting tools with which to explore liquid crystal (LC) systems; the motion of particles held in laser traps through LCs is perhaps the only approach that allows a low Ericksen number regime to be accessed. This offers a new method of studying the microrheology associated with micrometre-sized pa…
The kinetics of phase demixing in an aqueous two-phase system (ATPS) consisting of PEG/sodium citrate, with various PEG molecular weights (2000, 4000, and 6000) was investigated at 25°C. The rate of demixing of the phases (top/bottom) is essential to scale up the aqueous two-phase extraction (ATPE) process. The indivi…
The self-assembled monolayers (SAMs) derived from thionicotinamide (TNA), thioisonicotinamide (iTNA), and 5-(4-pyridyl)-1,3,4-oxadiazole-2-thiol (Hpyt) on gold have been characterized via surface-enhanced Raman scattering (SERS) as a function of pH and applied potential. Density functional theory calculations performe…
Structural analysis methodology relating to the dynamic analysis of ship structures is presented. The focus is on numerical analysis procedures, using the finite element method. The equations of motion are defined, and the corresponding solution methods described. Finite element modelling considerations for various le…
Abstract Der steigende Energiebedarf und der damit verbundene CO2‐Ausstoß bei gleichzeitig abnehmenden Reserven an fossilen Rohstoffen erfordert neue Konzepte zur nachhaltigen Energieerzeugung. Das sogenannte Adam‐und‐Eva‐Prinzip zur CO2‐freien Gewinnung von Methanol aus Kohle und durch Nuklearenergie wird aufgegriffe…
